Specification of Letters Patent.

Patented Mar. 25, 91 3.

To all whom it may conccwi:

Be it known that I, HENRY h IAYTROTT, a citizen oi. the United States, and a resident of Bridgeport, county of Fairtield, and State of Connecticut, have invented an improvement in Lamps, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawings representing like parts.

My invention relates to lighting apparatus, and more particularly though not exclusively to lamps for vehicles, and will be best understood by reference to the following description, when taken in connection with the accompanying illust 'ation of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims:

In the drawings :-l igure 1 is an elevation of a carriage lamp embodying my invention, showing the same as it appears when attached to the dash of the carriage, a portion of the dash being shown to illustrate its mode of attachmentthereto; F 2 is an elevation of the lamp as viewed from the right-hand side of Fig. 1; Fig. 3 is a dctail elevation on an enlarged scale of a portion of one end of the lamp illustrating the mode of fastening the lenses in place; Fig. 4 is a sectional view on an enlarged scale on line 4l of Fig. 1; and Fig. 5 is a similar longitudinal section partly broken away, showing the lenses inter-changed from their relative positions shown in Fig. 4.

Referring to the drawings, and to the embodiment of my invention which I have there disclosed for illustrative purposes, I have there shown a vehicle lamp having a lamp-supply section 6, and a lamp section 7-7 located at the side of the lamp-supply section and comprising a casing 8 within which is located a light-tln'nishing element 9. hile myinvention is applicableto kerosene, electric, and other lamps, l have herein chosen. to illustrate a lamp of the acetylene gas type, in which the lamp-supply section (3 consists of a generator, and the light-furnishing element't) consists ot a usual acety- 'lene gas burner, the latter being furnished with its supply trom the lamp-supply section by a suitable conductor 10 extending laterally from the lamp-supply section to the light-furnishing element 9.

l The casing 8 may be provided at one end with a door-frame 10 having an aperture 11, and may be provided at its other end with a fixed frame 12, having an aperture 13. Located in'these apertures are suitable interchangeable light-transmitting elements 14 and 15 respectively, herein in the form of lenses, the lens 14 being preferably though not necessarily red, and the lens 15 white, the former serving as a rear, or tail-light, and the latter as a front, or head-light, sometimes called a side-light. Associated with the lens 14 is a light-reflecting element- 16, herein consisting of a suitable reflector provided with an aperture 17 of suitable size to permit some of the rays of light to pass thcrethrough and through the lens 14, while the remaining rays of light strike the reflector and are reflected so as to pass through the lens 15.

The lens 14 and the reflector 16 and the lens 15 are interchangeably mounted in the casing in ,any suitable manner, as for example by providing the frames 10 and 12 respectively with annular grooves 18 and 19 forming seats for the lenses and reflector, and by providing'spring retaining rings 20 and 21 also seated in said grooves and hearing against the outer faces of the lenses in such a manner as to securely hold the latter in place, and yet. permit them to be instantly removed. For this purpose, the ring 20 may be provided with a grasping portion 22 (and the ring 21 may also be similarly provided) in a conveniently accessible position to be grasped by the fingers and drawn inwardly to contract the ring so as to permit. its withdrawal. The lens 14 and reflector 16 may then be removed and substituted for the lens 15, and the latter substituted for the former. In this way. the front of the lamp becomes theback and the back the front. The lamp may be provided with a light-transmitt-ing element 23, located at. the side of the casing S opposite the lamp-supply section '6 and at one side of the median axial line of the lenses. In other .words, the light-transmitting elements 14 and 15 are located in a plane transverse to a plane passing through the light-tarnishing element 9 and light-- transmitting element 23 The lamp may be provided with any suitable supporting means. as for example a bracket 2i located at the opposite side of i the lamp-supply section or generator (3 to that on which the lamp section 7 is located. Herein the bracket 24 is secured to the generator 6 by a band 25 surrounding the latter, and is clamped to the edge of a dash 26 in any suitable manner, as for ex-.

ample by means of a clamp-screw 27. By this means, the lamp may be placed on the other side of the carriage in such a manner as to project laterally therefrom, the position of the lamp section being suchuthat the rays of light will be shed without obstruc-- tion toward the front and rear of the vehicle. It will now be apparent that this same lamp may be utilized for either the right or left side of the carriage by simply reversing the ,same, and interchanging the lenses and the reflector, while the inner side light furnished by the light-transmitting element 23, and which is usually formed of red glass, serves for either the right or lefthand side light. This construction avoids the necessity of making lamps in pairs, that is to say, it avoids the use of. one

lamp particularly constructed for the lefthand side of the carriage, and another parspecific embodiment herein shown, but that extensive deviations from the illustrated form or embodiment of the invention may be made without departing from the principles thereof.

Having thus described one embodiment of my invention, what I claim is:

1. In a lighting apparatus, the combination with a lamp-supply section of a lamp section located laterally of the lampT-supply section, andcomprising a light-furnishing element, a pairof interchangeable, lighttransmitting elements located at opposite sides, respectively, of the light-furnishing element, and an interchangeably mounted apertured light-reflecting element associated with and disposed in front of one of the light-transmitting elements.

- 2. In a lighting apparatus, the combination with a lamp-supply section of a lamp able support, the median axial line of'said light-transmitting elements being located laterally of said lamp supply section and at the side of the latter opposite, said attaching means.

3. In a lighting apparatus, the combination of the lamp-cas1ng 8, provided with the grooves 18 and 19, a light-furnishing element, interchangeable lighttransmitting elements located at opposite sides respectively of the light-furnishing element with their marginal portions in said grooves, the retainingrings 20 and 21, and the apertured reflector 16 with its marginal portion in one of said grooves.

4. Li a lighting apparatus, the combina tion of a casing, a light-furnishing element within said casing, a pair of interchangeable light-transmitting elements located at opposite sides, respectively, of the lightfurnishing element, and ar. interchange-- ably-mounted apertured l1ghtreflect1ng ele-' ment interposed between said light-furnishing element and one of said light-transmitting elements.

ln testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
